I like the flexibility of two towers - do not know if you are looking 
for a contest type station or what... Having multiple towers also means 
your eggs are not in one basket so to speak....and.... you can always 
add a mid height tribander later on the taller tower later on...

While you go the group psyched put up two towers -
